Description

Technical Field

[0001] The invention belongs to the technical field of exposure lamps, and in particular relates to an ultraviolet exposure lamp used in a color filter exposure machine. Background Art

[0002] With the continuous development of semiconductor technology and optoelectronic technology, color filters are increasingly used in display technology, optical sensors, optoelectronic devices and other fields. In order to meet the needs of high-precision and high-efficiency production, color filter exposure machines came into being. As a key component of the exposure machine, the performance of the ultraviolet exposure lamp directly affects the production quality and efficiency of the color filter. At present, in order to achieve higher brightness, the existing ultraviolet exposure lamp will generate a higher temperature after being lit, which not only affects the service life but also increases the waiting time when replacing. In order to dissipate heat, the existing ultraviolet exposure lamps are all cooled by air cooling, that is, by installing a fan, the airflow passes through the reflector and the base in turn, thereby exporting the heat.

[0003] A Chinese patent application with application number 2016100878458 discloses a method for replacing an exposure machine and an exposure lamp, wherein the exposure machine comprises a housing, a light collecting mirror, an exposure lamp, and a plurality of jet devices; the plurality of jet devices can be extended and retracted above the light collecting mirror; when the exposure machine is working normally, the plurality of jet devices are retracted to the periphery of the top of the housing without affecting the direction of the light source during normal exposure; when the exposure lamp needs to be replaced, after the exposure lamp is turned off, the plurality of jet devices are extended to the outlet at the end thereof above the edge area of ​​the light collecting mirror, and the interior of the light collecting mirror and the exposure lamp are sprayed with air, so that the exposure lamp can be quickly cooled down, thereby effectively reducing the replacement time of the exposure lamp and improving the equipment utilization rate.

[0004] The above scheme is to use the jet device to spray air into the inside of the light collecting mirror, so as to quickly cool down the exposure lamp and prevent dust from adhering to the light collecting mirror. However, this method cannot dissipate heat while the exposure lamp is working. Moreover, whether it is the above jet device or the traditional fan, since a large ventilation path cannot be opened on the light collecting mirror, otherwise it will affect the light emission efficiency. Therefore, the air flow channel is narrow and cannot achieve a good heat dissipation effect. In addition, although wind can remove dust, the wind flow will also drive dust impurities in the air to impact the surface of the light collecting mirror, affecting the reflective effect of the light collecting mirror.

[0015] The advantages of the present invention are: 1. The present invention effectively conducts the heat generated by the lamp body to the insulating base through the arrangement of the heat-conducting rod and the first heat sink, and uses the fan to blow air to the first heat sink to dissipate heat, thereby improving the heat dissipation efficiency. This design can dissipate heat while the lamp body is working. Compared with the traditional horizontal air cooling method, this solution uses the longitudinal blowing method to not only ensure that the lamp body maintains stable luminous performance during long-term operation, thereby improving the production quality and efficiency of the color filter, but also this solution only blows air to dissipate heat inside the insulating base, avoiding the wind force directly impacting the reflector or the surface of the lamp body, thereby protecting the reflective effect of the reflector and improving the exposure quality and efficiency.

This heat dissipation method not only improves the heat dissipation efficiency, but also assists in improving the air-cooled heat dissipation effect. At the same time, the automatic coolant delivery mechanism in the present invention can automatically adjust the delivery of coolant according to temperature changes. When the temperature is too high, the expanding gas in the air cavity expands due to the heat, pushing the piston structure to move, causing the cover plate to open, and the coolant enters the insulating base after being gasified to dissipate heat. This intelligent adjustment mechanism ensures that the coolant is delivered in time when needed, avoiding unnecessary waste.

In short, for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Embodiment 1, combination Figure 1-3 A UV exposure lamp for a color filter exposure machine includes a lamp body 1, a reflector 2 and an insulating base 3. The reflector 2 includes a cover 4 and a neck 5. The cover 4 and the neck 5 are integrally formed. One end of the lamp body 1 is arranged in the neck 5. The neck 5 is arranged in the insulating base 3 by gluing or screwing. Halogen gas, mercury, argon gas, etc. are sealed inside the lamp body 1. Two electrodes are extended on both sides of the inner side of the lamp body 1. When a given high voltage is applied, the glow discharge started between a pair of electrodes is converted into arc discharge, and the mercury evaporated and excited by the arc emits ultraviolet light, which is reflected on the reflector 2 to the corresponding substrate.

[0041] Combination Figure 1The portion of the neck 5 located in the insulating base 3 is connected to a heat-conducting rod 6, on which a plurality of first heat sinks 7 are arranged, a bracket 8 is arranged inside the insulating base 3, on which a fan 9 is installed, and the blowing direction of the fan 9 is arranged directly opposite to the plurality of first heat sinks 7, and the top and bottom of the insulating base 3 are respectively provided with a first vent 10 and a second vent 11, and the blowing direction of the fan 9 is perpendicular to the axial direction of the neck 5. When the lamp body 1 generates heat during operation, the heat will be transferred to the heat-conducting rod 6 through the reflector 2, and then dissipated to the insulating base 3 through the first heat sink 7 on the heat-conducting rod 6. At this time, by driving the fan 9 to rotate, the heat can be blown away, thereby achieving a heat dissipation effect. Through the arrangement of the heat-conducting rod 6 and the first heat sink 7, the heat generated by the lamp body 1 is effectively conducted to the insulating base 3, and the fan 9 is used to blow the heat sink to dissipate heat, thereby improving the heat dissipation efficiency. This design can dissipate heat while the lamp body 1 is working. Compared with the traditional horizontal air cooling method, this solution uses the longitudinal blowing method to not only ensure that the lamp body 1 maintains stable luminous performance during long-term operation, thereby improving the production quality and efficiency of the color filter, but also this solution performs blowing and heat dissipation inside the insulating base 3, avoiding direct wind impact on the reflector 2 or the surface of the lamp body 1, thereby protecting the reflective effect of the reflector and improving the exposure quality and efficiency.

[0042] Combination Figure 4 , the first vent 10 is connected with a first air guide pipe 12, the second vent 11 is connected with a second air guide pipe 13, the other side of the first air guide pipe 12 and the second air guide pipe 13 are connected and connected with a heat exchange device 14. Under the wind force of the fan 9, the heat will enter the second air guide pipe 13 with the air flow, and then enter the first vent 10 again through the first air guide pipe 12 after heat exchange and cooling by the heat exchange device 14. The heat exchange device 14 can directly adopt a traditional heat sink structure. The arrangement of the first air guide pipe 12, the second air guide pipe 13 and the heat exchange device 14 actually provides a physical barrier between the inside of the device and the external environment. The inside of these pipes is smooth and dust is not easy to accumulate, thereby effectively preventing external dust from directly entering the inside of the device. By connecting the vent to the air guide pipe, the way for dust to directly enter the inside of the device is reduced. In the traditional air-cooled heat dissipation method, the vent is often directly exposed to the external environment and is easily invaded by dust. However, this solution relatively isolates the vent from the external environment through the arrangement of the air guide pipe, thereby reducing the possibility of dust entering.

[0043] Combination Figure 5-6The insulating base 3 is connected to an automatic coolant delivery mechanism, which includes a delivery seat 15, which is integrally formed with the insulating base 3 and is made of a heat-conducting material of the delivery seat 15. A liquid reservoir 16 is provided in the delivery seat 15, in which a low-boiling-point coolant is stored. An evaporation delivery pipe 17 and a coolant replenishment pipe 18 are provided on the liquid reservoir 16. The evaporation delivery pipe 17 is connected to a delivery port 19, which is arranged toward the inside of the insulating base 3. The end of the coolant replenishment pipe 18 away from the liquid reservoir 16 is a replenishment port, which is arranged toward the outside of the insulating base 3. The low-boiling-point coolant can be a mixture of 50% ethanol and 50% water, or a mixture of 35% n-butanol and 65% water. The azeotropic point of the mixed coolant is about 55°C-65°C. The coolant in the liquid reservoir 16 will boil into gas after absorbing a certain amount of heat, and enter the insulating base 3 through the evaporation delivery pipe 17 to absorb the heat in the insulating base 3. Since the first flow conduit 12 and the second flow conduit 13 realize the closed circulation of gas, the air-cooling heat dissipation effect in the insulating base 3 will be reduced. Therefore, an automatic coolant delivery mechanism is provided. When the temperature is too high, the heat will be transferred to the liquid reservoir 16, and the coolant in the liquid reservoir 16 will be evaporated into the insulating base 3 to absorb the heat, thereby assisting in improving the air-cooling heat dissipation effect.

[0044] In order to prevent the loss of coolant, a cover plate 20 is provided on the outside of the injection port 19, an opening groove 21 is opened on the side wall of the insulating base 3 located at the cover plate 20, and a plug rod 22 is provided on both sides of the cover plate 20. A piston cavity 23 matching the plug rod 22 is provided on the insulating base 3, and the plug rod 22 extends into the piston cavity 23 and is connected to a piston structure 24. An air cavity 25 connected to the piston cavity 23 is also provided on the insulating base 3, and the air cavity 25 is filled with expansion gas. A first return spring 26 is connected to the side of the piston structure 24 away from the plug rod 22, and the other side of the first return spring 26 is connected to the side wall of the air cavity 25. Figure 7As shown, at room temperature, the first return spring 26 pulls the plug rod 22 into the piston cavity 23 through elastic force. At this time, the delivery port 19 is in a closed state, and the low-boiling point coolant in the liquid storage tank 16 will not overflow. When a large amount of heat is transferred to the delivery seat 15, the expansion gas in the air cavity 25 in the delivery seat 15 expands due to heat. The expansion gas is preferably hydrogen. The expansion speed and degree of hydrogen after heating are more significant. The thermal expansion behavior of hydrogen can be approximately linear. When the temperature rises by 40°C, the volume of hydrogen will increase by 17.8%. After the hydrogen expands, it pushes the piston structure 24 to move toward the cover plate 20, so that the cover plate 20 is in an open state. At this time, the mixed coolant can also be in a gaseous state and enter the insulating base 3 through the cover plate 20. The automatic coolant delivery mechanism can automatically adjust the delivery of the coolant according to the change in temperature. When the temperature is too high, the expansion gas in the air cavity 25 expands due to heat, pushing the piston structure 24 to move, so that the cover plate 20 is opened, and the coolant enters the insulating base 3 after being gasified to dissipate heat. This intelligent regulation mechanism ensures that coolant is delivered in time when needed, avoiding unnecessary waste.

[0045] Combination Fig. 9 , a sealing ring is provided on the piston structure 24 to achieve a sealing effect, but after a long time, the sealing ring is easy to wear, especially when hydrogen is heated and expanded, it is easier for hydrogen to overflow. In this embodiment, the piston structure 24 includes a first piston body 29 and a second piston body 30, and the first piston body 29 and the second piston body 30 are both provided with corresponding sealing rings. The first piston body 29 is provided with a chamber 31 and an air chamber 32 inside, and the chamber 31 and the air chamber 32 are connected to each other. The outside of the air chamber 32 is connected to a gas sealing ring 33, and the gas sealing ring 33 is a ring-shaped airbag structure. One end of the second piston body 30 is connected to a push rod 34, and the push rod 34 extends into the chamber 31 and is connected to a third piston body 35. The side of the third piston body 35 close to the air chamber 32 is connected to a second return spring 36. When the hydrogen begins to expand, it first pushes the second piston body 30 to move to the left. The second piston body 30 first drives the push rod 34 to compress the second return spring 36, and squeezes the gas in the air chamber 32 at the same time. The gas in the air chamber 32 is compressed and drives the gas sealing ring 33 to expand. After the gas sealing ring 33 expands, it can play an auxiliary sealing effect. When the second piston body 30 moves to contact the first piston body 29, the gas sealing ring 33 expands to the limit. The first piston body 29 and the second piston body 30 drive the plug 22 to move to the left together, thereby opening the cover plate 20. When the hydrogen no longer shrinks due to heat and cooling, the gas sealing ring 33 will also shrink, thereby reducing wear and improving the service life. By adding a gas sealing ring 33 to the traditional piston structure 24 and using the gas pressure in the air chamber 32 to drive the gas sealing ring 33 to expand when the hydrogen expands, a significant improvement in the sealing effect is achieved, which effectively prevents hydrogen from overflowing from the piston structure 24 when it expands due to heat, ensuring the safety and stability of the system.

[0046] Combination Figure 5 , Figure 7 and Figure 8 In this embodiment, a plurality of diffusion ports 28 are arranged around the delivery port 19, and the plurality of diffusion ports 28 are diffused as a whole. The diffusion ports 28 are arc-shaped pipe ports connected to the evaporation delivery pipe 17, and a plurality of diffusion ports 28 form a trumpet-shaped diffusion opening structure around the evaporation delivery pipe 17. When the coolant evaporates, it is sprayed into the inside of the insulating base 3 at a wider angle through the diffusion ports 28. The cooling capacity of the coolant after evaporation can be more evenly distributed in the insulating base 3, and the heat can be more effectively absorbed and taken away, avoiding local overheating or excessive temperature gradients. The system instability caused by the large temperature gradient is avoided. A spoiler device is provided in the evaporation delivery pipe 17, and the spoiler device includes a spoiler 27, which is twisted in a spiral shape and the edges of the spoiler 27 are connected to the inner wall of the evaporation delivery pipe 17. The spoiler device can reduce the velocity fluctuation of the fluid in the evaporation delivery pipe 17, thereby reducing the impact and friction of the fluid on the inner wall of the pipe and improving the stability of the fluid. This stability helps to maintain the continuity and uniformity of the coolant vapor and ensure the stable operation of the heat dissipation system.

[0047] Embodiment 2, combined Figure 10-11This embodiment is a further improvement of the heat exchange device 14. The heat exchange device 14 includes a heat exchange tube 37, a plurality of second heat sinks 38 and a water cooling mechanism. One side of the heat exchange tube 37 is connected to the first flow guide tube 12, and the other side of the heat exchange tube 37 is connected to the second flow guide tube 13. The plurality of second heat sinks 38 are arranged on the heat exchange tube 37. When the hot air flows through the heat exchange, the heat is absorbed by the heat sink and transferred to the outside, thereby achieving a cooling effect. The water cooling mechanism includes a water supply ring 39. The water supply ring 39 is arranged at one end of the heat exchange tube 37. The bottom of the water supply ring 39 is connected to a plurality of cooling water pipes 40. The plurality of cooling water pipes 40 are axially attached to the surface of the heat exchange tube 37 and pass through the second heat sink 38. The other end of the heat exchange tube 37 is provided with a water receiving ring 41. The ends of the plurality of cooling water pipes 40 away from the water supply ring 39 are connected to the water receiving ring 41. One side of the water supply ring 39 is connected to a circulating water supply pipe 44, and one side of the water receiving ring is connected to a circulating water outlet pipe 45. A plurality of tube grooves 42 are provided inside the second heat sink 38, and the cooling water pipe 40 passes through the tube grooves 42 and is connected to the tube grooves 42. A connecting groove 43 is connected between adjacent tube grooves 42, and a single tube groove 42 is connected to adjacent tube grooves 42 through the connecting grooves 43 on both sides. The cooling water pipe 40 is arranged around the heat exchange tube 37 as a whole, and can absorb the heat of the heat exchange tube 37 and the heat sink, thereby achieving comprehensive heat transfer and dissipation. When the hot air flows through the heat exchange tube 37, the heat is absorbed by the heat sink and transferred to the outside. At the same time, the cooling water pipe 40 in the water cooling mechanism further absorbs the heat of the heat exchange tube 37 and the heat sink, thereby achieving a double heat dissipation effect. The tube grooves 42 and connecting grooves 43 provided inside the heat sink enable the cooling water pipe 40 to pass through and be connected to the tube grooves 42, forming a continuous heat dissipation channel. This design not only increases the heat dissipation area, but also improves the heat transfer efficiency. The design of the connecting groove 43 also enables the cooling water in the blocked cooling water pipe 40 to flow into the adjacent cooling water pipe 40 through the connecting groove 43 on one side of the blocking point, and then flow into the original cooling water pipe 40 again from the adjacent cooling water pipe 40 through the connecting groove 43 on the other side of the blocking point, making the flow of cooling water in the pipeline more flexible and smooth. Due to the existence of the connecting groove 43, even if a cooling water pipe 40 is blocked, it does not need to be disassembled and repaired immediately, ensuring the continuous water cooling.

[0048] Embodiment 3, combined Fig.12This embodiment shows another embodiment of the heat exchange device 14. The heat exchange device 14 includes a serpentine heat pipe 46, a plurality of third heat sinks 47 and an air cooling fan 48. One side of the serpentine heat pipe 46 is connected to the first guide pipe 12, and the other side of the serpentine heat pipe 46 is connected to the second guide pipe 13. The plurality of third heat sinks 47 are in a square structure and are sequentially arranged on the serpentine heat pipe 46. The air cooling fan 48 is arranged on the side of the plurality of third heat sinks 47. The plurality of third heat sinks 47 are in a square structure and are sequentially arranged on the serpentine heat pipe 46. Since the design of the serpentine heat pipe 46 increases the surface area and efficiency of heat exchange, and the square structure of the heat sink also maximizes its surface area, the heat exchange device 14 can achieve efficient heat dissipation effect. These heat sinks can quickly transfer heat from the serpentine pipe to the surrounding air. The square structure of the heat sink maximizes its surface area, thereby improving the heat dissipation efficiency. The air cooling fan 48 is located on the side of the heat sink, and accelerates the flow of surrounding air by generating forced convection, thereby improving the heat dissipation effect.

[0049] Embodiment 4, combined Fig.13 The difference between this embodiment and the first embodiment is that a lens cover 54 is provided at the front end of the reflector 2 in this embodiment. In the case where high-intensity ultraviolet irradiation is required, the lens cover 54 can focus the light emitted by the ultraviolet lamp into a more concentrated light beam, thereby improving the utilization rate and irradiation intensity of the light. At the same time, the lens cover 54 can also protect the reflector 2 from being contaminated by dust, dirt or other impurities, thereby extending the service life of the reflector 2. However, the lens cover 54 also forms a closed space, making it difficult for the reflector 2 to dissipate heat. For this reason, a first heat dissipation cavity 49 is provided on one side of the cover 4, a second heat dissipation cavity 50 is provided on the other side of the cover 4, an annular cavity 51 is provided on the inner side of the opening edge of the cover 4, and the annular cavity 51 is connected to the first heat dissipation cavity 49 and the second heat dissipation cavity 50, and a first ventilation cavity 52 and a second ventilation cavity 53 are provided on the inner side of the neck 5, the first ventilation cavity 52 is connected to the first heat dissipation cavity 49, and the second ventilation cavity 53 is connected to the second heat dissipation cavity 50. When the fan 9 drives the airflow, part of the airflow enters the first heat dissipation cavity 49 through the first ventilation cavity 52, then enters the second heat dissipation cavity 50 through the annular cavity 51, and is discharged from the second ventilation cavity 53, forming an air heat dissipation channel in the inner wall of the reflector 2. This design can ensure that the heat generated inside the reflector 2 is effectively dissipated, preventing the performance and life of the device from being affected by overheating.

[0050] A closed opening structure 55 is formed between the lens cover 54 and the opening of the cover 4. A first ventilation slot 56 and a second ventilation slot 57 are provided on the inner side of the neck 5. The first ventilation slot 56 communicates with the closed opening structure 55 and the first ventilation cavity 52, and the second ventilation slot 57 communicates with the closed opening structure 55 and the second ventilation cavity 53. When the fan 9 is working, air can enter the inside of the cover 4 through the first ventilation slot 56 and the second ventilation slot 57, forming air convection, thereby effectively taking away the heat inside the cover 4 and improving the heat dissipation efficiency.

[0051] Combination Figure 14-15 The first ventilation slot 56 and the second ventilation slot 57 are both provided with an expansion airbag 58, which is filled with expansion gas. The expansion airbag 58 is used to close the first ventilation slot 56 and the second ventilation slot 57 under high temperature. If the temperature is high, the coolant in the liquid reservoir 16 will become gaseous. In order to prevent the gaseous coolant from entering the opening of the reflector 2, the corresponding ventilation slot is closed by the expansion airbag 58. Only after the lamp body 1 is closed and the temperature drops, the ventilation slot can be opened to increase the cooling speed.

[0052] Combination Fig.16 In this embodiment, a plurality of fourth heat sinks 59 are provided on the outer side of the cover 4. The fourth heat sinks 59 enable heat to be transferred to the surrounding environment more quickly. This helps to reduce the operating temperature of the cover 4 and improve the heat dissipation efficiency. The diameters of the plurality of fourth heat sinks 59 decrease from the middle to both sides. The fourth heat sink 59 located in the middle has the largest diameter, and the ones on both sides are smaller. Since the wind direction is uncertain, a structure with a high middle and low sides is set. No matter which side the wind comes out from, it will not affect the heat dissipation effect. More importantly, through the step-shaped structure, the wind will form vortices when passing through different fourth heat sinks 59, which can further enhance the heat dissipation effect.
